LAPTOP PERFORMANCE AFFECTED WHEN USING MULTIPLE DISPLAYS

Using a 15" MacBook Pro with 2.4GHz and 8 megs of ram running Lion, I created and ran a video-intensive Keynote file successfully from beginning to end. But when connected to an external monitor, the entire laptop became sluggish, slow and non-responsive. Keynote would start and stop during playback, and even Desktop minimize a nimations ran very slowly... Any ideas WHY???

How much ram in the MB?
How much free space on the HD?

When using multiple displays, is it possible to only have full screen zoom (universal access) only effect one display?

I am visually impaired which makes it difficult for me to use computers. The zoom feature in Mac OS is extremly useful to me and is the first reason I choose mac over windows. Although, now that I've been using a mac for 8 years, I would pick a mac any day! For my work flow, I utilize two displays. It would help me greatly if there was a way to only effect one display with the zoom feature.
Thank you for your input,
Zachary

You can set the zoom to ONLY follow your mouse (And adjust the size of the "zoom window" that follows it). I used to use this with Quick time Editing when I had a 13" iMac.

How do you use multiple displays with a MacBook Pro and iMac

I have an iMac and a MacbookPro laptop both upgraded to OS X 10.9 (Mavericks). I'd like to use multiple displays with them. Can I do this without an Apple TV? They are both on the same network. If I can, can someone please give some instructions on how this can be done?
Thanks!

Both computers have ports for external monitors. Check your user manuals. Only one display can be added to the MBP, but newer iMacs have dual Thunderbolt ports.
Do your own Google research to learn what to do, but reading your manuals should be all you really need. It' not rocket science yet.

Performance hit when using a FirePro GPU?

Hey there!
I'm interested in purchasing a cheap ATI FirePro V4900 or similar GPU in order to take advantage of my 10 bit TFT when using Photoshop. I was wondering if I have to expect a performance hit when using PS 6.0 with such a card as opposed to a normal "gamer" GPU like the NVidia 670 GTX when :
- performing normal file handling, opening PSD files, paning, zooming, brushing, etc.
- applying some of the newer GPU-enhanced filters like Liquify, Oil Paint, Iris Blur, 3d enhancements, etc.
- actually applying/rendering a more demanding fliter such as Iris Blur?
Does anyone know about this? I'm afraid I could not find any benchmarks at all except for the one on Tomshardware regarding OCL, but that one does not include professional GPUs...
Thanks for any info in advance!

There will not be synchronization when the method of A
is being called. The method 1) certainly saves memory
space, but will the performance be hurt since there
will only be one object accessed by multiple threads?
Or maybe it doesn't matter?If there is no synchronization, it will not matter. Threads execute methods. Methods do not run on Objects. The Object is just data that is implicitly linked to the method.
Just make sure it's safe to keep the method unsynchronized.

ExecuteNonQuery doesnt return number of rows affected when used with PL/SQL

ExecuteNonQuery doesn't return number of rows affected when used with PL/SQL but returns -1. The documentation says ExecuteNonQuery method of OracleCommand returns the number of raws affected but when used with PL/SQL, it returns -1 even the update statement successfully executes and affects multiple records with no exeptions thrown.
However, if ExecuteNonQuery is used with update sql statement in the asp.net code it returns number of rows affected correctly. Does anybody know why ExecuteNonQuery behaves like this?
I am using ODP.NET that comes with Oracle Client 11g. The version is 2.111.6.20 of ODP.NET, Oracle database server is 10g.

You can get the rowcount in the stored procedure via SQL%ROWCOUNT and then pass it out as a parameter.
For example:
SQL> create or replace procedure updatesal(v_deptno in number, v_rowsaff out number) as
2 begin
3 update emp set sal = sal * 5 where deptno = v_deptno;
4 v_rowsaff := SQL%ROWCOUNT;
5 end;

Performance problem when using CAPS LOCK piano input

Dear reader,
I'm very new to Logic and am running into a performance problem when using the CAPS LOCK-piano-keyboard for input of an instrument: when I'm not recording everything is fine and the program instantly responds on my keystrokes, but as soon as I go into record-mode there is sometimes a delay in the response-time (so I press a key and it takes up to half a second longer before the note is actually played).
Is there anything to do about this to improve performance (for example turning of certain features of the application), or should I never use the CAPS LOCK keyboard anyway and go straight for an external MIDI-keyboard?
Thanks and regards,
Tim Metz

Does your project have Audio tracks and just how heavy it is, how many tracks? Also, what kind of Software Instrument do you use?

Why is quicktime slower when using multiple mdat atoms

Hi,
I've been trying to generate a mov file and I noticed that the more mdat atoms I put in my mov file the more the file takes time to load on QuickTime, iTunes.
Even worst, on the iPhone the file takes more than 3 minutes to load.
If there are too many mdat atoms quicktime even says that the file is invalid ( error -2004 or -2002, I don't remember exactly).
Why is quicktime/iTunes slower when using multiple mdat atoms ?
Thanks,

Yeah! Problem solved: It's a QT issue.
Cause: Mac Update Software downloaded a faulty QT.
Solution: Download QT from Apple's QT site.
Great to have the Video back

Performance issues when using AQ notification with one consumer

We have developed a system to load data from a reservation database to a reporting database
A a certain point in the proces, a message with the identifier of the reservation is enqueued to a queue (multi-consumer) on the same DB and then propagated to a similar queue on the REP database.
This queue (multi-consumer) has AQ notification enabled (with one consumer) which calls the queue_callback procedure which
- dequeues the message
- calls a procedure to load the Resv data into the Reporting schema (through DB link)
We need each message to be processed ONLY ONCE thus the usage of one single subscriber (consumer)
But when load testing our application with multiple threads, the number of records created in the Reservation Database becomes quite large, meaning a large number of messages going through the first queue and propagating to the second queue (very quickly).
But messages are not processed fast enough by the 2nd queue (notification) which falls behind.
I would like to keep using notification as processing is automatic (no need to set up dbms_jobs to dequeue etc..) or something similar
So having read articles, I feel I need to use:
- multiple subscribers to the 2nd queue where each message is processed only by one subscriber (using a rule : say 10 subscribers S0 to S10 with Si processing messages where last number of the identifier is i )
problem with this is that there is an attempt to process the message for each subscriber, isn't there
- a different dequeuing method where many processes are used in parallel , with each message is processed only by one subscriber
Does anyone have experience and recommendations to make on how to improve throughput of messages?

Hi, thanks for your interest
I am working with 10.2.0.4
My objective is to load a subset of the reservation data from the tables in the first DB (Reservation-OLTP-150 tables)
to the tables in the second DB (Reporting - about 15 tables at the moment), without affecting performance on the Reservation DB.
Thus the choice of advanced queueing (asyncronous )
- I have 2 similar queues in 2 separate databases ( AND Reporting)
The message payload is the same on both (the identifier of the reservation)
When a certain event happens on the RESERVATION database, I enqueue a message on the first database
Propagation moves the same message data to the second queue.
And there I have notification sending the message to a single consumer, which:
- calls dequeue
- and the data load procedure, which load this reservation
My performance difficulties start at the notification but I will post all the relevant code before notification, in case it has an impact.
- The 2nd queue was created with a script containing the following (similar script for fisrt queue)
dbms_aqadm.create_queue_table( queue_table => '&&CQT_QUEUE_TABLE_NAME',
queue_payload_type => 'RESV_DETAIL',
comment => 'Report queue table',
multiple_consumers => TRUE,
message_grouping => DBMS_AQADM.NONE,
compatible => '10.0.0',
sort_list => 'ENQ_TIME',
primary_instance => '0',
secondary_instance => '0');
dbms_aqadm.create_queue (
queue_name => '&&CRQ_QUEUE_NAME',
queue_table => '&&CRQ_QUEUE_TABLE_NAME',
max_retries => 5);
- ENQUEUING on the first queue (snippet of code)
o_resv_detail DLEX_AQ_ADMIN.RESV_DETAIL;
o_resv_detail:= DLEX_AQ_ADMIN.RESV_DETAIL(resvcode, resvhistorysequence);
DLEX_RESVEVENT_AQ.enqueue_one_message (o_resv_detail);
where DLEX_RESVEVENT_AQ.enqueue_one_message is :
PROCEDURE enqueue_one_message (msg IN RESV_DETAIL)
IS
enqopt           DBMS_AQ.enqueue_options_t;
mprop           DBMS_AQ.message_properties_t;
enq_msgid           dlex_resvevent_aq_admin.msgid_t;
BEGIN
DBMS_AQ.enqueue (queue_name => dlex_resvevent_aq_admin.c_resvevent_queue,
enqueue_options => enqopt,
message_properties => mprop,
payload => msg,
msgid => enq_msgid
END;
- PROPAGATION: The message is dequeued from 1st queue and enqueued automatically by AQ propagation into this 2nd queue.
(using a call to the following 'wrapper' procedure)
PROCEDURE schedule_propagate (
src_queue_name IN VARCHAR2,
destination IN VARCHAR2 DEFAULT NULL
IS
sprocname dlex_types.procname_t:= 'dlex_resvevent_aq_admin.schedule_propagate';
BEGIN
DBMS_AQADM.SCHEDULE_PROPAGATION(queue_name => src_queue_name,
                                        destination => destination,
latency => 10);
EXCEPTION
WHEN OTHERS
THEN
DBMS_OUTPUT.put_line (SQLERRM || ' occurred in ' || sprocname);
END schedule_propagate;
- For 'NOTIFICATION': ONE subscriber was created using:
EXECUTE DLEX_REPORT_AQ_ADMIN.add_subscriber('&&STQ_QUEUE_NAME','&&STQ_SUBSCRIBER',NULL,NULL, NULL);
this is a wrapper procedure that uses:
DBMS_AQADM.add_subscriber (queue_name => p_queue_name, subscriber => subscriber_agent );
Then notification is registered with:
EXECUTE dlex_report_aq_admin.register_notification_action ('&&AQ_SCHEMA','&&REPORT_QUEUE_NAME','&&REPORT_QUEUE_SUBSCRIBER');
- job_queue_processes is set to 10
- The callback procedure is as follows
CREATE OR REPLACE PROCEDURE DLEX_AQ_ADMIN.queue_callback
context RAW,
reginfo SYS.AQ$_REG_INFO,
descr SYS.AQ$_DESCRIPTOR,
payload RAW,
payloadl NUMBER
IS
s_procname CONSTANT VARCHAR2 (40) := UPPER ('queue_callback');
r_dequeue_options DBMS_AQ.DEQUEUE_OPTIONS_T;
r_message_properties DBMS_AQ.MESSAGE_PROPERTIES_T;
v_message_handle RAW(16);
o_payload RESV_DETAIL;
BEGIN
r_dequeue_options.msgid := descr.msg_id;
r_dequeue_options.consumer_name := descr.consumer_name;
DBMS_AQ.DEQUEUE(
queue_name => descr.queue_name,
dequeue_options => r_dequeue_options,
message_properties => r_message_properties,
payload => o_payload,
msgid => v_message_handle
-- Call procedure to load data from reservation database to Reporting DB through the DB link
dlex_report.dlex_data_load.load_reservation
( in_resvcode => o_payload.resv_code,
in_resvHistorySequence => o_payload.resv_history_sequence );
COMMIT;
END queue_callback;
- I noticed that messages are not taken out of the 2nd queue,
I guess I would need to use the REMOVE option to delete messages from the queue?
Would this be a large source of performance degradation after just a few thousand messages?
- The data load through the DB may be a little bit intensive but I feel that doing things in parallel would help.
I would like to understand if Oracle has a way of dequeuing in parallel (with or without the use of notification)
In the case of multiple subscribers with notification , does 'job_queue_processes' value has an impact on the degree of parallelism? If not what setting has?
And is there a way supplied by Oracle to set the queue to notify only one subscriber per message?
Your advice would be very much appreciated
Philippe

How can I better use multiple displays as if they were multiple computers?

In Mavericks I read online that multiple display support is the best it's ever been, but it's still very frustrating. Is there any way to get the "multi displays are different spaces" option to act more as it promises? Photoshop, for instance, refuses to let me move all of its control windows to my calibrated display, forcing me to go back and forth between my Eizo and internal monitors; one for its colors and the other for the tool pallates.
I want to use my MacBook display just for email and such, so I don't want to close the lid, but I wish it could be really segrigated. The experience I'm looking for is sort of like 2 computers with a shared keyboard and mouse. One dock per display is desprately needed. Can that be done?
Also allowing each display to have one applicatioin currently in front when multiple input devices are present would be greatly appreciated. I could then keep one keyboard and tablet in front of the Eizo and use the internal for use on the Macbook - if the OS could learn my setup it could really be the best of the benefits of having 2 computers and just one. Shared Clipboard and one Space colaborating seamlessly with another, while having the abillity to work entirely within one space and then move to the other while waiting for a command to finish executing, or to go back to the file system to open more work.
This is so close to perfect but it has a few really frustrating limitations. Any advice?
thank you
-Jeremy

Setting Photoshop monitor profiles when using dual displays?

I'm using a Macbook Pro connected to an Apple Cinema Display under OS 10.5.8. Both monitors are calibrated and I export from Lightroom to Photoshop in ProPhoto. The Photoshop working colour space is also ProPhoto so there is no mismatch there.
When in dual display mode I like to have my Photoshop application on the Macbook screen and the photo I'm working on shown on the Cinema Display. In fact, I couldn't work any other way because the laptop's screen is not at all suitable for precision work.
I noticed that when I send an image from Lightroom to Photoshop CS4 for further editing the colours were off in Photoshop. This lead me to check the monitor profile used by Photoshop and I saw it was using the Macbook Pro .icc profile. This seems to be used even if the image is displayed in the external display. Selecting the Cinema Display as "default" in ColorSync doesn't change the situation. As a result, the colours as displayed by Photoshop are incorrect.
The only "solution" I have found is to either go to System Preferences > Displays and select the external monitor as the principal one (which is inconvenient because it negates many of the advantages of using dual monitors) or setting the Cinema Display's .icc profile for the Macbook Pro as well (which makes it the one chosen by Photoshop but means I'm only working wiht one correctly calibrated monitor).
Is there a solution to this problem? Ideally I want to have both my monitors calibrated and Photoshop detect which one I'm using to view my photo. Failing that, I would like to have both monitors calibrated and "tell" Photoshop to use the Cinema Display as the principal monitor.I don't want .
Many thanks!

Thanks for your reply!
I'm not too worried about 10.6 because I'm not using it ( I reverted to 10.5.8 precisely because of the colour issues).
I don't really understand your reply. My problem is that if Photoshop uses my Mabook Pro profile as the "monitor profile" my pictures - as displayed on the Cinema Display - look different in Lightroom and in Photoshop. It's as if Lightroom is "aware" of which of the two displays is being used whereas Photoshop can only deal with one at a time. I would like to know if this analysis is correct and what I can do so that Photoshop displays my photographs the same way as Lightroom does on each of my two displays.

Solve Drive self-ejects and System Hangs when using MULTIPLE external drives!

I've discovered what I think is the underlying reason for many folks reporting similar problems. I bet that I can predict the GUIDs of the drives/docks/cases you're having trouble with! I bet that if you look in Disk Utility, if you click on the drives, you'll find "Connection ID 13757101839304263"!
Oh and if you look in System Profiler and click on 'FireWire' or 'USB' you'll find the GUID 0x30E002E0454647 !
What are the odds? I shouldn't be able to predict them; theyr'e supposed to be unique, after all, but google that number and you'll see that a great many devices all use that GUID.   (13757101839304263 in decimal is the same thing as 30E002E0454647 in hex.)
Mac OS seems to rely on them to be unique, and has fits when they aren't. I haven't found a total solution yet, but in the meantime, running this in Terminal can help:
sudo kextload /System/Library/Extensions/IOFireWireFamily.kext/Contents/PlugIns/AppleFWOHCI.k ext/
Sometimes it helps to run this first to unload before loading the kext (kernel extension):
sudo kextunload /System/Library/Extensions/IOFireWireFamily.kext/Contents/PlugIns/AppleFWOHCI.k ext/
Enter your password if/when prompted, of course.
In most cases, if you contact your hard drive manufacturer, they'll provide a utility that will fix the drive so that it actually has a truly unique GUID.
I'm mad at Cavalry for hiding the problem and refusing to fix it, W.R.T. the two 1TB HDs I bought from them for around $500, when that was the going price.
I figured it'd be helpful to create a user tip off the discussion in this thread: Disk Drive ejecting itself - https://discussions.apple.com/thread/2151621?start=615&tstart=0     This is my first attempt to create a tip. I'm not sure I'm doing it right, but here goes.

Sorry but this is just a really bad idea.
1. The airport is ancient.. your speed will be terrible.
2. Hubs filled with USB drives are never reliable.. disks refuse to spin up.. become unavailable.
No.. don't do it.
Plug USB3 hub into the mini and use multiple decent hard drives .. that is fine.. use thunderbolt hub.. use thunderbolt drives if you can afford it.. but never use USB drives on the network.
3. Time Machine is not reliable to external drive on Airport Extreme.. Apple do not support it in any Extreme except the latest one.
If you want the material available to the network buy a NAS. You can buy a cheap NAS of 8TB or so and another 8TB of USB drives which you plug into the NAS for backup.. however.. iphoto is not supposed to ever be put on network drives..
Apple explicitly states you will corrupt it.
http://support.apple.com/kb/TS5168 Although mostly about FAT32           it adds network drives.
http://support.apple.com/kb/HT1198
And I quote
It's recommended that you store your iPhoto library on a locally mounted hard drive. Storing your iPhoto library on a network share can lead to poor performance, data corruption, or data loss. If you use both iPhoto and Aperture with the same library, using a Mac OS X Extended formatted volume is recommended. For more information, see Aperture: Use locally mounted Mac OS X Extended volumes for your Aperture library.
For backup of the drives.. use Carbon Copy Cloner.. it is much better than TM as you can setup different job.. TM is really a single function.. !!

Close the macbook pro when using external display

Hi
I would like to know if is recomended to close the laptop when using an external display? i ask because i read somewhere that the system take ventilation through the keyboard? is better to work with the laptop always open? or doesn't matter if is closed?

Third opinion...
I had a 2.16GHz 15" MacBook Pro that I used as a presentation machine at some trade shows in '07 and I once ran the machine with the lid closed, hooked up to an overhead projector looping a movie for 11 hours. When I finally shut it down for the night the machine was pretty warm (it was well ventilated) and was immediately usable. Out of curiosity the next day I ran it with a lid slightly cracked and the unit was significantly warmer at the completion of my day.
The only thing I could justify as the temperature difference is that the LCD was on and causing heat in addition to the video card. I guess I would have been curious to leave the lid slightly cracked and then manually set the backlight to off.

ISE Not Identifying AD Group Attributes when using Multiple ISE Servers

So we have multiple ISE Servers with differing personas. I was having an issue with our new ISE setup not identifying AD Group Attributes when using them in Authorization rules.
We have 2- 3395 appliances running Admin and Monitoring/Troubleshooting Personas and 2- 3395 appliances running as Policy server personas. We are running v1.1.1.268 with the latest two patches.
I was unable to pull Active Directory Group Attributes in any of my Authorization rules. After Resyncing all the boxes with the Primary Administration box I was able to do this. There is no bug listings for this occurance nor do we have Smartnet to call support for other reasons. I thought this might be useful to someone who is having the same issue and is unable to figure it out with TAC
-CC

Absolutely. All units said in-sync after setting their personas.
Here is our layout:
ISE-ADM-01 Admin-Primary, Monitoring-Secondary
ISE-ADM-02 Admin-Secondary, Monitoring-Primary
ISE-PDP-01 Policy Only
ISE-PDP-02 Policy Only
I synced one at a time starting with ADM-02. After completing the other two boxes. Active Directory Attribs were pulled down when using them in the Ext Group within my Authz rules.
